OBJECTIVETo study the characters of the treatment of perioperative period in fractures with diabetes mellitus (DM) and the effect of diabetes on the treatment of them.

METHODSTo retrospectively analyze the clinical data of 97 fracture patients with DM (DM group) who accepted operation. Compare the difference of the average hospitalized length, medical cost and the incidence of postoperative complications with the controls.

RESULTS(1) Insulin dosage was less in postoperative period (0.5 +/- 0.2) U.d(-1).kg(-1) than steady period (0.7 +/- 0.2) U.d(-1).kg(-1) and operative period (0.7 +/- 0.3) U.d(-1).kg(-1), the difference is significant (P < 0.05); (2) There were more complications in DM group than that in the control group before operation. The fractured patients with DM could receive operation after preoperative treatment and improving micro-circulation; (3) Compared with control group, DM group had longer preoperative preparation period of in-hospital duration, and higher in-hospital medical costs; (4) There were no significant difference between DM group and control group (P > 0.05) in postoperative complications and wound healing.

CONCLUSIONSFractured patients with DM should take effective methods to treat complications of DM and do adequate preparation for the operation. Rational treatment of preoperative complications is very important for preventing postoperative one and guarantee operation successful. But the longer of hospitalized length is, the higher of in-hospital medical costs are.
